Ingano nubunini bwibibaho byumuzunguruko

Muri iyi nyandiko ya blog, tuzasesengura ubunini busanzwe nubunini bwibibaho byumuzunguruko.

Ikibaho cyumuzunguruko cya Ceramic kiragenda gikundwa cyane mubikorwa bya elegitoroniki kubera imiterere yabyo ndetse nimikorere ugereranije na PCB gakondo (Bicapuwe byumuzunguruko). Bizwi kandi nka ceramic PCBs cyangwa ceramic substrates, izi mbaho ​​zitanga imicungire myiza yubushyuhe, imbaraga za mashini nyinshi hamwe nibikorwa byiza byamashanyarazi.

1. Incamake yibibaho byumuzunguruko:

Ikibaho cyumuzunguruko ceramic gikozwe mubikoresho byubutaka nka oxyde ya aluminium (Al2O3) cyangwa nitride ya silicon (Si3N4) aho kuba ibikoresho bisanzwe bya FR4 bikoreshwa muri PCB gakondo. Ibikoresho bya ceramic bifite ubushyuhe bwiza bwumuriro kandi birashobora gukwirakwiza ubushyuhe mubice byashyizwe ku kibaho. Ceramic PCBs ikoreshwa cyane mubisabwa bisaba ingufu nyinshi nibimenyetso byumuvuduko mwinshi, nka electronics power, amatara ya LED, icyogajuru hamwe nitumanaho.

2. Ibipimo nubunini bwibibaho byumuzunguruko:

Ingano yumuzunguruko wububiko nubunini birashobora gutandukana bitewe nibisabwa byihariye nibisabwa. Nyamara, hari ubunini busanzwe nubunini busanzwe bukoreshwa mu nganda. Reka twibire muri izi ngingo:

2.1 Uburebure, ubugari n'ubugari:
Ikibaho cyumuzunguruko cya Ceramic kiza muburebure butandukanye, ubugari n'ubugari kugirango bihuze n'ibishushanyo bitandukanye. Uburebure busanzwe buva kuri milimetero nkeya kugeza kuri milimetero magana, mugihe ubugari bushobora gutandukana kuva kuri milimetero nkeya kugeza kuri milimetero 250. Kubijyanye n'ubugari, mubisanzwe ni 0,25 mm kugeza kuri mm 1.5. Nyamara, ingano irashobora gutegurwa kugirango ihuze umushinga ukeneye.

2.2 Umubare w'ibyiciro:
Umubare wibice mu kibaho cyumuzunguruko ceramic ugena ubunini bwacyo nibikorwa. Ceramic PCBs irashobora kugira ibice byinshi, mubisanzwe kuva kumurongo umwe kugeza kuri esheshatu. Ibice byinshi byemerera guhuza ibice byinyongera hamwe nibisobanuro, byorohereza ibishushanyo mbonera byumuzunguruko.

2.3 Ingano:
Ceramic PCBs ishyigikira ubunini butandukanye bitewe nibisabwa. Imyobo irashobora kugabanywamo ubwoko bubiri: ushyizwe mu mwobo (PTH) kandi udashyizwe mu mwobo (NPTH). Ubusanzwe umwobo wa PTH uri hagati ya 0,25 mm (mil 10) kugeza kuri mm 1.0 (40 mili), mugihe ubunini bwa NPTH bushobora kuba buto nka mm 0,15 (6 mil).

2.4 Kurikirana n'ubugari bw'umwanya:
Uburebure n'umwanya mubugari bwumuzunguruko wa ceramic bigira uruhare runini mugukomeza ibimenyetso byerekana neza imikorere yamashanyarazi. Ubugari busanzwe bwuburebure buri hagati ya 0,10 mm (4 mil) kugeza kuri 0,25 mm (10 mil) kandi buratandukanye ukurikije ubushobozi bwo gutwara. Mu buryo nk'ubwo, ubugari bw'ikinyuranyo buratandukanye hagati ya 0,10 mm (4 mil) na 0,25 mm (10 mil).

3. Ibyiza byimbaho ​​zumuzunguruko:

Ni ngombwa gusobanukirwa ingano nubunini busanzwe bwibibaho byumuzunguruko, ariko ni ngombwa kimwe gusobanukirwa ibyiza batanga:

3.1 Gucunga ubushyuhe:
Ubushyuhe bukabije bwibikoresho byubutaka butuma ubushyuhe bukwirakwizwa neza mubice byingufu, bityo bikongerera sisitemu muri rusange.

3.2 Imbaraga za mashini:
Ikibaho cyumuzunguruko ceramic gifite imbaraga zubukanishi, bigatuma zirwanya cyane ibintu bitandukanye byo hanze nko kunyeganyega, guhungabana ndetse nibidukikije.

3.3 Imikorere y'amashanyarazi:
Ceramic PCBs ifite igihombo gito cya dielectric hamwe no gutakaza ibimenyetso bike, bigafasha gukora inshuro nyinshi no kunoza ubuziranenge bwibimenyetso.

3.4 Miniaturisation hamwe nigishushanyo kinini:
Bitewe nubunini bwazo hamwe nubushuhe bwiza bwumuriro, imbaho ​​zumuzunguruko za ceramic zituma miniaturizasi hamwe nubushakashatsi bwimbitse mugihe gikomeza gukora amashanyarazi meza.

4. Mu gusoza:

Ingano isanzwe nubunini bwibibaho byumuzunguruko wa ceramic biratandukanye bitewe nibisabwa nibisabwa. Uburebure n'ubugari bwazo biva kuri milimetero nkeya kugeza kuri milimetero magana, naho ubunini bwazo buva kuri mm 0,25 kugeza kuri mm 1.5. Umubare wibice, ubunini bwumwobo, nubugari bwa trike nabyo bigira uruhare runini muguhitamo imikorere nimikorere ya ceramic PCBs. Gusobanukirwa nibi bipimo ningirakamaro mugushushanya no gushyira mubikorwa sisitemu ya elegitoroniki ikora neza ikoresha imbaho ​​zumuzunguruko.
